Subject: [OSM-legal-talk] use of maptiles
Hello,
i develop a commercial application which makes use of the tile material
from osm. I read Heavy use (e.g. distributing an app that uses tiles
from openstreetmap.org) is forbidden without prior permission from the
System Administrators. See below for alternatives. in
http://wiki.openstreetmap.org/wiki/Tile_usage_policy.
Now i ask my self the question what is heavy use of tile materials.
First of all, I do not speak for the system administrators. They make
the decisions on what to block, and how. What I write is based on my
experience seeing what has caused load problems in the past
There is not a level at which your use is guaranteed to never be
considered heavy use or guaranteed not to be blocked. If that is a
requirement, you need to enter into a contract with a commercial
provider who will set out pricing terms. Also remember that if your use
does become heavy use, you can change to a commercial service right
away, because you didn't hardcode the tile.openstreetmap.org location
into your app, since the terms prohibit that.
The following are generally heavy use
- Downloading tiles by area for later offline use
- Consuming a noticable portion of resources (see
http://munin.openstreetmap.org/openstreetmap/tile.openstreetmap/index.html
and
http://munin.openstreetmap.org/openstreetmap/render.openstreetmap/index.html
)
- Distributing a smartphone map app targeted at consumers that uses
tile.openstreetmap.org by default.
- A commercial map-based website in production
- Anything that neglects or tries to get around the usage policy
technical requirements
The following are typically not heavy use
- Use on an about page indicating the location of a head office or
similar location
- Use in development
